Voice Coil With Real Time Stroke Control

Technology break through in voice coil control, high frequency signal processing algorithms provide fretting wear tests with less than 5 micron stroke and characterizes fretting wear from micron to macro scale. Ultra sensitive piezo based load cells, combined with a robust design, high stiffness holders, and low floor noise allow quantitative fretting wear characterization of materials, interfaces, thin films, components, and more.

N

The Smallest Controllable Stroke - 5 um to 4 mm, up to 300Hz

Real time stroke, frequency monitoring, and correction using LVDT.

N

High Reliability - Flexure Design

The flexural suspension guides the magnet assembly without
bearings.

N

Environmental Control, Surface Electrical Measurement

Humidity, temperature, inert gas, and electrical measurements for
real-life simulation.

N

High Frequency Response Force Sensors

Piezo based sensors measure friction force with ultra high accuracy at high frequency reciprocating test.

High Speed Controllers

The Fretting Module Is perfect for testing surface damage that occurs between two contacting surfaces experiencing oscillatory displacement of a small amplitude.

Test Debris

Debris formation from asperity contacts
Oxidation at contacting surface because of humidity, temperature, or chemical composition change
Oil, lubrication starvation regimes causing wear
Wear due to electric discharge
Repetitive collision between surfaces
Fatigue related cracks – onset of debris
Polymerization of organic materials at surface
Fine powdered debris – highly oxidized
Residual steady stage flow of debris
Diffusive wear
Melting wear

Specification Summary

Reliable and Customizable

To simulate real life scenarios, tests can be done in controlled environmental conditions. Easy to use and intuitive data interpretation makes this tester an ideal tool in hands of researchers or quality control engineers.
